Daniel is an Amazon best-selling author, solopreneur, data scientist, and teacher.

He has self-published a series of technical books used as textbooks in universities in the United States and Spain. In the last 25 years, he had many jobs—developer, data scientist, teacher, writer—but he's none of them. After figuring out his own path, he decided to share his experience and insights with others in his upcoming book "You're Not Your Job: Going Above and Beyond for Yourself."
